Add some close encounters to Fallout 4 with this alien invasion mod

pcgamer.com:

We've known that aliens exist in the Fallout universe for a long time now, with crashed spaceships and alien corpses appearing in several games in the series. Heck, you can get beamed up to a mothership in an expansion for Fallout 3, and there's an alien invasion event in Fallout 76.

In Fallout 4 you can find a spaceship and fight a single living alien, but modder RascalArt decided it was time to finally begin a proper alien invasion. In the Zetans—Alien Invaders in the Commonwealth mod(opens in new tab), extraterrestrial visitors are done being coy and let their true intentions be known. The occupation of Earth has begun with flying saucers and alien ground forces.

I can't direct you to a specific place to find the extraterrestrial visitors—the aliens of the Zetans mod seem to pop up as random encounters, just like lots of other vanilla Fallout 4 enemies. I installed the mod and began exploring the world looking for them, eventually coming across an amazing sight. As I was crossing a field near a ruined bridge, a flying saucer slowly rose from the ground, spun around, and began attacking me.

And it was kinda awesome to see! I was so transfixed by the sight of a flying saucer I just sort of stood there as it began strafing me with energy weapons. I couldn't just gawk, though, because an alien soldier also opened fire on me from the ground. When I'd finally killed them both (the saucer took a long time because I didn't have any heavy weapons on me) I got a couple rewards. First, the saucer hit the ground and detonated in a brilliant explosion, and second, the alien grunt I killed had a Zetan pulse rifle on him. Perfect. I'll use their advanced technology against them.

It's not just flying saucers and simple soldiers
